Studies have shown that color content and complexity of the image are important discriminating features. [1]

Features initially chosen

  • Important color features: red, green and blue histogram percentages.

  • Important complexity features: entropy, population of long lines (trees) and short lines (bushes and small branches).

  • LSBE Image - note the "clutter" and dull colors
    HSBE Image - a good deal of greenery and trees; high visual penetration
